The menu of small plates served in Restaurant Guy Savoy's elegant Bubble Bar gives you a chance to taste some of the highly lauded French chef's creations without dire damage to the pocketbook. The best deal is four "small bites" items for $40 -- not cheap, but nowhere near the $290 per person for the Menu Prestige in the main dining room. Everything is served as either a small bite (actually three or four bites, tapas style) or a big bite, about the size of a normal appetizer. Taste Monsieur Savoy's famous artichoke and black truffle soup or his oysters in ice gelée. The Champagne will set you back a bit, though. The least expensive bubbly by the glass is a private label blanc de blancs at $29 a glass. The most expensive? That's $75 a glass for Krug Grande Cuvée, naturellement.
